Rusted Omega 3220 challenge

[AlecMac]

Hi, mid repair of a rusted Omega Speedmaster reduced, first time working on a 3220. In hindsight not the best decision as It's not always clear if parts are suppose to come apart or not...anyway I've worked through most of that now and am left with one mystery part. Pictured below. It defiantly needs to come out, and it definitely needs replacing, but in the 3220 service doc I'm using it's only ever shown in place and it's not named, I guess its the operating lever / upper operating lever?

In the picture from the service doc it's the part at 4 o'clock with the lubrication point on it. This is the first step that adds parts to the main plate and its shown already in place.

The second photo shows the rusted part on the watch I'm working on

The last pic is just for context and shows the movement and it's rust.

 

Some my questions are, what is it, and how do I replace it?

Looks like the flyback yoke intermediate lever.

Thank you, and can see from the part on eBay how it’s fitted. Why omega didn’t include it in the service doc we’ll never know.   https://www.ebay.co.uk/itm/134737785564

It's because under normal circumstances it's not a serviceable item.

Edit

Just realised that the 55.083 is shown in the Technical Guides. What documents have you got?

I had to do a similar rust mitigation project on an omega 1140 speedy reduced. Yeah it looks like an operating lever. The DD parts aren't particularly well finished I have noticed, so even trying to sand and polish this down might cause issues. And these parts are expensive!
